Content type distribution and API traffic share on Cloudflare Radar

Radar now includes two new charts on the traffic page that provide deeper insights into the composition of HTTP traffic: a content type distribution chart and an API traffic share chart.

Content type distribution

The new Content type chart displays the distribution of HTTP response content types, grouped into high-level categories. A traffic type selector allows filtering by human, bot, or all traffic. The existing Bot vs. Human chart also gained a content type category filter, allowing users to see the bot/human split for specific content categories.

Content type categories:

• HTML — Web pages (text/html)
• Images — All image formats (image/*)
• JSON — JSON data and API responses (application/json, *+json)
• JavaScript — Scripts (application/javascript, text/javascript)
• CSS — Stylesheets (text/css)
• Plain Text — Unformatted text (text/plain)
• Fonts — Web fonts (font/*, application/font-*)
• XML — XML documents and feeds (text/xml, application/xml, application/rss+xml, application/atom+xml)
• YAML — Configuration files (text/yaml, application/yaml)
• Video — Video content and streaming (video/*, application/ogg, *mpegurl)
• Audio — Audio content (audio/*)
• Markdown — Markdown documents (text/markdown)
• Documents — PDFs, Office documents, ePub, CSV (application/pdf, application/msword, text/csv)
• Binary — Executables, archives, WebAssembly (application/octet-stream, application/zip, application/wasm)
• Serialization — Binary API formats (application/protobuf, application/grpc, application/msgpack)
• Other — All other content types

The CONTENT_TYPE dimension and contentType filter are available on the HTTP summary, timeseries groups, and timeseries endpoints.

API traffic share

The new API traffic chart shows the percentage of dynamic (non-cacheable) HTTP request traffic that is API-related. API traffic is identified by JSON or XML response content types (application/json, application/xml, text/xml) on HTTP requests that returned a 200 status code. A traffic type selector allows switching between human traffic, bot traffic, or all traffic.

The API_TRAFFIC dimension is available on the existing HTTP summary and timeseries groups endpoints. An apiTraffic filter (API or NON_API) can also be applied to HTTP timeseries requests to retrieve raw request counts for API-only or non-API traffic.
